Please help me with all problems,, due tommorow :(

Diego is making a circular table. He is cutting the largest circle possible from a piece of square wood with sides 6 feet long.

Flauer [41]

Area of wood = 6x6 = 36
area of circle = 3.14x9 = 28.26
left over = 36 - 28.26 = 7.74

Answer:

See explanation

Step-by-step explanation:

1. For the given graph:

A. Max is at -1 and

B. Min is at -5.

C. The midline of a sinusoidal function is the horizontal center line about which the function oscillates above and below. Hence, the midline has the equation

$y=\dfrac{Max+Min}{2}=\dfrac{-1+(-5)}{2}=\dfrac{-6}{2}=-3$

D. The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function, so

$Amplitude=\left|\dfrac{-1-(-5)}{2}\right|=2$

E. The period of a periodic function is the horizontal length of one complete cycle (the distance between two consecutive maximums), then the period is

$\dfrac{3\pi}{2}-\dfrac{\pi}{2}=\pi$

F. The frequency of a trigonometric function is the number of cycles it completes in a given interval. This interval is generally 2π radians (or 360º) for the sine and cosine curves. Actually,

$Frequency=\dfrac{2\pi }{\pi}=2$

G. The equation of the function is

$f(x)=2\sin \left(2\left(x-\dfrac{\pi}{2}\right)\right)-3$

2. For the given function $f(x)=3\sin \left(\dfrac{\pi x}{2}\right)+2$

A. Max is at 5 and

B. Min is at -1.

C. The midline of a sinusoidal function is the horizontal center line about which the function oscillates above and below. Hence, the midline has the equation

$y=\dfrac{Max+Min}{2}=\dfrac{5-1}{2}=\dfrac{4}{2}=2$

D. The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function, so

$Amplitude=\left|\dfrac{5-(-1)}{2}\right|=3$

E. The period of a periodic function is the horizontal length of one complete cycle (the distance between two consecutive maximums), then the period is

$|5-1|=4$

F. The frequency of a trigonometric function is the number of cycles it completes in a given interval. This interval is generally 2π radians (or 360º) for the sine and cosine curves. Actually,

$Frequency=\dfrac{2\pi }{4}=\dfrac{\pi}{2}$

G. The graph of the function is attached.
